Compress PDF

Reduce the size of large scanned or image-heavy PDFs — privately, in your browser.

This compressor works by re-rendering pages as optimized images, so it shrinks scanned or image-heavy PDFs the most. Text becomes part of the image (no longer selectable). For text-only PDFs that are already small, savings may be minimal.

Everything runs locally in your browser — your PDF is never uploaded to a server.
